| Abstract | The MM mass range examined is 0<or=M/sup 2/<or=7.3 GeV/sup 2/ with t (the proton four momentum transfer squared) in the interval 0.2<or= mod t mod <or=0.3 GeV/sup 2/. Narrow resonances (R/sub 1/, R/sub 2/, R /sub 3/, S, T, and U) with cross sections and widths reported by the CERN missing mass group are ruled out by the data. The cross sections d/sup 2/ sigma /dtdM/sup 2/ show evidence for triple factorizability of the form d/sup 2/ sigma /dtdM/sup 2/ approximately=D(P/sub B/)A(M /sup 2/)G(P/sup 2/) where P/sub B/ is the incident beam momentum, and P/sup 2/ is the perpendicular component of the detected proton's momentum with respect to the beam direction.
